The .ICM to which I was referring are profiles created by X-Rite for the factory calibration of the OLED panel.

I'm not sure if I have previous posted, but my personal X1YogaGen2 with the 14.0 "WXGA OLED display has NONE of the defects/artifacts that my 15.6" OLED 4K display exhibits on my P53. No dots, no grid lines, no blotches at low brightness levels. It's too bad that all of this exists to some extent on my P53 without any possibility of resolution.

What makes you say that there's no possibility of resolution? These display issues seem to me like manufacturing or quality control problems that should be covered by the warranty.

I didn't mean to imply that the issue shouldn't be covered by warranty. My point was that all of the posters in the forum who have experienced grid lines, dots, banding and replaced the panel still had the same or similar issues after service. I hope that there will be a differenct p/n that can be used for warranty service that will correct things.

Same here with my P1G2. Vertical bands noticeable on dark backgrounds and low brightness. Also the annoying fabric pattern grid with light backgrounds. Quite sad to pay +500€ than the FHD and have this issues.
What I did is change all my themes from "dark" to strictly #000000. This way the panel looks great. Actually better. But the panel is obviusly an absolute fail.

I'm seeing the same with the 4k OLED sceen on the P53.
In my case a dark rectangular area in the top-left and a few horizontal and vertical bands.
It seem to be just a minor light intensity difference.
Shouldn't this be fixable with some sort of callibration?
In general, I love the colours and as echefede says; pure black looks finally good.

If you got the X-Rite factory calibration, you could change the gamma via the profiles. I'm using the default profile which is the normal corrected calibration. Others have reported that DCI-P3 works best for them.
One other item that I have used has affected the color intensity: Display HDR Test from the MS Store. I've run that application and right at the end there is a gamma setting screen (actually 2). Run that test and setup the screen acording to the last two panels. I believe that you'll find the display much improved.

The positions of the darker areas in your display are at the same relative positions as on my screen, but yours appear to be a bit wider. The leftmost area shows a bit of red which I believe is the color calibration that you've chosen (DCI-P3). I think that the banding is a characteristic of the OLED panel as I've read about this on TV screens as well, just arranged a bit differently. I previously posted what calibration that I've used on my P53. The DCI-P3 seems to exacerbate the issue because it lowers the gamma. The "default" calibration seems to mitigate the banding to a degree. Also, it seems that as the panel gets used, the center brighter area gets lower. It's a shame that the panel suffers from this aberration as it is so good at higher levels of brightness and color. I'm just going to live with it just like I've lived with my backlight leakage on my P1Gen1 4k UHD touchscreen.
